The present invention relates to a paper cutting machine used as an office machine, and a method for cutting paper with the present paper cutting machine. Conventional cutters support one end of the blade, grasp the handle of the other end, press the overlapping paper to cut it, or use a rotary blade to engage the edge of the base of this rotary blade, There was a cut. This conventional cutter is designed to cut paper by a shearing force applying the principle of scissors. When cutting the overlapping paper by using shearing force based on the principle of scissors, the cutting edges of the paper are different from each other, thereby limiting the number of sheets of paper. The previous cutters also suffered from the problem of staples being missed or dull when staples were incorrectly cut, and the need to replace expensive foundation blades with new ones.

The paper cutting machine according to the present invention has a plate, which has a supporting portion for supporting the rail, and is mounted on one end of the plate (safe mounting). One end of the rail is pivotally supported by a support via a pin so that the rail pivots up and down around the pin. On which the rail is fixed, a slider moves along the rail, and the slider is provided as a circular cutting edge (hereinafter simply referred to as a "cutting edge") for paper cutting. On the opposite side of the rail is provided a spring holder which is elastically supported by a spring and a hook is attached to the other end of the rail, ie the end of the rail is remotely operated from the support plate. Since the guide part seated at the other end of the plate, that is, the end of the plate of its width, is to be remotely operated from the support part, the end of the rail is provided as a hook fixed to the guide part. The rail support part is provided with two guide pins in order to press both sides, and each presses the both sides of a rail by the elastic means from each spring.

The guide pin rotates the pin edge and, when moving up and down, functions as a means for preventing lateral waves of the rail. The slider mounted so as to be movable on the rail mainly comprises a slider main body and a cutter side slider main body which is a cutter holder. The cutter holder mainly comprises the cutter support plate, the slide (sliding) part, the slider fixing screw, and the circular cutter blade. Since the cutter blade is rotatably attached to the slider portion in such a manner, the polygonal pillar is provided on the support plate, and is fitted in accordance with the polygon hole provided in the cutter blade. The paper cutting machine provided as described above is used as follows.

The rails are turned so as to rotate around the pins so that the paper is laid on the plate and cut, so that the rails are lowered. Therefore, the paper is firmly sandwiched between the plate and the paper holder, the far end of the rail is guided by the guide parts, and is securely mounted by means of the hook. The paper is cut by moving the slider along the rail. In this cutting process, the cutter rotates and cuts into the paper.

The first object of the present invention is to prevent preservation of the surface of the overlapping paper sheet to be meshed with each other to be cut at the same time.

A second object of the present invention is to minimize the possibility that the cutter is broken or the blade is pulled out, thereby extending the life of the cutter. Further, a third object is to improve the practicality of the paper cutting machine as an office machine, which is convenient for changing the cutter blade.

A fourth object of the present invention is to propose that the paper is held in a balanced state and cut to a highly accurate desired size.

According to the paper cutter of the present invention, the paper is reliably fixed and cut between the paper holder and the plate. The reason why the paper is reliably fixed between the paper holder and the plate is because the paper holder is elastically supported and the rail is firmly fixed at both ends by the support and the hook. As the paper is reliably fixed and the rail is firmly fixed at both ends, the slider is adapted to move along the rail. Therefore, the cutter cuts it while rotating and cuts it into paper. Thus, there is no need to worry about the cut surfaces of the overlapping paper that are meshed together and cut at the same time.

The rail is formed in parallel with a grid of scales as a guide pin provided on the supporting portion, and there are guide parts provided on a plate, so that the paper can be cut to a desired size with high accuracy. The slider constitutes three split main shaft parts, i.e., a cutter holder, a cutter side slider body, and a slider body, and the slider is fixed on an arbitrary cutter rail. The cutter blade can be easily replaced with a new one by removing the cutter support plate, and the cutter holder can move up and down through the elasticity from the spring, and the cutter blade can be rotated so that the cutter blade can be pressed against the paper. The force applied is limited by the spring force.

Thus, when it encounters an external object (such as a staple or the like), the cutter moves vertically during rotation, so the cutter moves vertically, away from the external object, and away from the spring from the spring.

In this way, the cutter is protected from being subjected to any emergency forces so that the cutter can be prevented from falling out or breaking.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, the rail support portion 41 is securely mounted at one end of the plate 38, and the rail 35 is supported by this rail support portion 41.

The guide pin 46 is projected under the rail 35 when pushed up to the point indicated by reference numeral 35 'by the operation of the spring 60, as shown in FIG. The amount that the guide pin 46 protrudes is limited by the flange 46a, and when the rail 35 is pushed down, the end (spherical) of the guide pin 46 slides on the side surface, The support part body 44 is pushed back against the elasticity from the spring 47.

Thus, when pushed down, the rail 35 is prevented from being laterally undulated by the pressure means generated therethrough via the guide pin 46.

Referring again to FIG. 1, reference numeral 36 denotes a paper holder, and the paper holder 36, as shown in FIGS. 3 and 5, extends through the rail 35. It is attached to the opposite side of the rail 35 via 59. The paper holders 36 are each elastically protruded downwards by the resilient means from the springs 56 fixed thereon. Reference numeral 49 in FIG. 1 denotes a guiding part, which is securely mounted at the other end of the plate 38. Since the guide part 49 has a concave end having a V-shaped cross section as shown in FIG. 4, and is a V-shaped recess formed in a predetermined size, the rail 35 is a V-shaped recess without any looseness. It is fixed to the part. Reference numeral 50 denotes a hook provided at the far end of the rail 35, and the hook 50 is attached to the rail 35 via the pin 63 as shown in FIG.

Since the hook 50 is subjected to elasticity from the spring 62, the hook 50 is connected to the upper surface of the plate 38. As shown in FIG. 4, the cover plate 51 is provided with a bore (hole) for receiving the hook 50.

Referring back to FIG. 1, the support plate 54 is attached to the table 53, and since the scale graduation line 55 is drawn perpendicular to the support plate 54, the scale graduation line 55 has various sizes. It is comfortable on a piece of paper.

The scale graduation line 55 extends in parallel with the rail 35 when it is fixed to both ends by the rail support part 41 and the guide part 49. As shown in FIG. Reference numeral 39 denotes a cutter mat.

As shown in FIG. 5, the table 53 is securely mounted to the plate 38 by means of the bolt 61, while the cutter mat 39 is fixedly replaceable in the recess formed in the plate 38. have. Reference numeral 26 shown in FIG. 5 indicates a cutter provided along the edge of the paper holder 36.

The cutting end of the cutter 26 is disposed on the cutter mat 39. In FIG. 1, reference numeral 40 denotes a slider fixed on the rail 35, and the slider 40 will be described in detail later. Referring to Fig. 7, reference numeral 1 denotes a cutter holder, 2 denotes a slider body, 3 denotes a cutter side slider body, and 4 denotes a cap.

The slider body 2 has a top guide 18 fixed on the rail 35, and has an upper guide side surface 19 and a lower guide surface 20. Reference numeral 21 denotes a paper pressing portion 21 formed at the lower end of the slider body 2.

The cutter side slider body 3 each has a vertical slide (slid) groove 12 formed in its two opposing side walls. The slide portions 11 of the cutter holder 1 are fixed in the slide grooves 12, respectively.

The stopper 8 formed on the cutter holder 11 is connected to the stopper 13 disposed on the cutter side slider body 3, and reference numeral 22 denotes a lower guide, and 16 is indicated. It is a paper press.

The cutter holder 1 mainly constitutes the cutter support plate 7, the slide part 11, and the binder plate 27 as shown in FIG. 8. The circular cutter 26 has a hexagonal bore 42 provided at the center as shown in FIG.

The cutter equipment surface of the support plate 7 is rotatably supported in the bore provided in the center of the handle part 6, and is provided by the hexagonal pillar 34 which has a hexagonal terminal end. A magnet 33 is disposed in the installation surface of the support plate 7 near the hexagonal pillar 34.

The cutter holder 1 is assembled as follows, and the cutter blade 26 is attached to the support plate 7 by fixing the hexagonal pillar 34 provided on the support plate 7 as shown in FIGS. 8 and 9. It is fitted with a hexagonal baud rate provided in the tunnel 26. Therefore, the cutter 26 is supported by the magnet 33 magnetically and is not dropped.

Thus, the cutter blade 26 is attached to the supporting plate 7 in advance, and then the distal end of the hexagonal pillar 34 is fitted to the bore 320 provided in the slide portion 11, and the supporting plate 7 It is fixed to, and is fixed to the slide portion 11 with the cutter 26.

Thus, the slider binding bolt 28 provided integrally with the binding plate 27 is fitted through the through holes 30 and 31 to be bound by the nut means.

At this time, the distal end of the hexagonal pillar 34 passes through the bore 32 in the slide portion 11, it is fixed to the boss (29). The cutter holder 1 thus assembled is fixed to the slide groove 12 in the cutter side slider body 3 as shown in FIG. In the embodiment provided as above, the slider 40 is assembled to the rail 35 in the manner described below.

The cutter side slider main body 3 has a cutter holder 1 fixed therein, and the slider main body 2 has a method of enclosing the rail 35 from both sides. The top surface 17 of the main body 2 is fixed to the ceiling 15 of the cutter side slider body 3.

After the spring 10 is fixed to each spring latch 9, the cap 4 is fixed to the slider bodies 2 and 3, while they are fixed to each other from the upper side, while the spring 10 ), The screws 33 pass through the through holes 24 and 14, and are screwed into the threaded bores (holes) 25, respectively.

Thus, the spring 10 is pressed between the cap 4 and the cutter holder 1 supported by the connection between the stopper 8 and the 13, thereby lowering the cutter holder 1 downward. Make it elastic. The elasticity level from the spring 10 is adjusted by appropriately tightening the screw 23.

Even if the screws 23 are not tightened, the elasticity from the spring 10 acts to press the ceiling 15 of the cutter side slider body 3 against the top surface of the slider body 2, and the two slider bodies. The fixed connection between (2) and (3) is secured by means of the cap (4).

Therefore, the slider body 2 and the cutter side slider body 3 remain in their bound body.

10 shows the slider 40 assembled as described above. When the paper is to be cut, the overlapped paper sheet is first placed on the support plate 54 shown in FIG. 1 to arrange the paper sheet. Thus, the sheets of paper are placed along the scale scale 55 in accordance with the paper size.

Then, the rail 35 is lowered, so that the overlapped sheets of paper are pressed by the paper holder 36, and at the same time the rail 35 is guided by the guide pin 46, the rail 35 Is prevented from undulating horizontally.

Therefore, there is no fear of the paper sheets supported by the paper holders 36 engaged with each other. The end of the rail 35 is fixed to the guide part 49, so that both ends of the rail 35 are fixedly positioned by the rail support 41 and the guide part 49, and the rail 35 The silver is securely mounted by the hook 50 means, and eventually the paper sheet must be supported.

Since both ends of the rail 35 are fixed, and the scale graduations 55 are parallel to each other, the support plate 54 and the rail 35 (paper holder 36) are perpendicular to each other.

Next, a paper cutting method will be described. As shown in FIG. 10, the overlapped paper sheet 37 is supported on the plate 38 by means of the paper holder 36, and the slider 40 is pressed down. While sliding along the rail 35. Although the slider 40 is supposed to press the overlapped sheet of paper, the cutter 26 does not take excessive force because it is only an elastic object from the spring 10 and does not directly attract the force there. to be.

Thus, breakage of the cutter 26 is prevented. When an external object such as a staple is caught, the cutter 26 is in such a way to jump over it and move away from it, so that the cutter 26 is rotatable, moving up and down through the spring 10. It can be.

Thus, the cutter 26 is prevented from falling off. Moreover, the cutter blade 26 is adapted to stop from rotation with respect to the hexagonal pillar 34 through a fitting connection between the pillar 34 and the hexagonal hole (bore) 42.

To change the cutter 26, the nut 5 is loosened, the support plate 7 is removed by grasping the handle 6, and the cutter 26 is changed into three.

The reason why the nut 5 and the handle 6 are elongated is to protect the user's hand from contacting the cutter 26 during the cutting operation, so that the paper pressing portions 16 and 21 are also cut. It serves as a means for limiting the cutting depth of the tunnel 26 to prevent damage to the cutter 26.

The cutter blade 26 is vertically pressed so that the overlapping paper sheet 37 is cut into the paper sheet, so that the paper edges that are rotated to be cut in such a state and interlocked with each other are cut without any concern.
